Taylor will lead a session called “Optimising Your Margin in an Ever-Changing Market,” which will show attendees how customer insight-driven merchandising and marketing is helping retailers around the world address margin squeeze, improve financial performance and enhance their price image.

Smith will lead the “End-to-End Promotion Management: Combining Clever Science, Smart Planning and Efficient Execution” session, which will show how DemandTec is helping retailers gain margin points through more effective, targeted promotions. Attendees will hear a range of case studies that will provide insight into what it takes to achieve success using DemandTec’s end-to-end promotion management software services.

“Retailers can now effectively combine the science of optimisation with an end-to-end promotion process, from vendor deal entry through promotion planning and ad execution. Companies implementing next generation solutions are transforming the way they plan and execute their promotions, and reaping significant bottom line results,” said Smith.
